Three-dimensional photonic microstructures produced by electric field assisted dissolution of metal nanoclusters in multilayer stacks

摘要

The formation of three dimensional (3D) photonic microstructures by the locally selective dissolution of metal clusters embedded in dielectric multilayer stacks is presented. Dissolution of clusters is performed by the simultaneous application of electric field and temperature. The produced photonic structures show a highly tailorable optical behavior that combines the interferential effects of multilayer stacks and the surface plasmon resonance of non-dissolved metal clusters. Due to its feasibility and the possibility to widely modify the optical properties of the resulting structures, the current approach represents a promising method for the production of novel components based on 3D-metallodielectric photonic structures.
